Can anyone help on Validations

Question

Hi SDNers,
I am facing a problem with validations.
Here is my requirement.
I had a field (Phone Number). In that business will enter either Lanline Number ot Mobile Number.
Ex - 0444 12345678 or 044 12345678 These are land line numbers.
ex:- Mobile numbers : 1234567891.
Here I need a validatin in this way.
1) First we need to check is NUL or not.
2) Then the phone shold not start with other than 0 or 1.
3) If its starts with 1 then there should not be a Space between those numbers.
4) If Landline number starts with 0 we need to check area code first 4 digits or 3 digits and space than phone number.
    Ex -  0444 12345678 or 044 12345678. (We need to check phone number is in this format or not)
Any Help?
Thanks
Kiran

Hi,
This is working. Just paste this
IS_NOT_NULL(Phone Number) AND LEFT(Phone Number,1)<=1 AND IF(LEFT(Phone Number,1)=1,ABS(Phone Number)=Phone Number) AND (IF(LEFT(Phone Number,1)=0,LEN(ABS(Phone Number))=2 OR IF(LEFT(Phone Number,1)=0,LEN(ABS(Phone Number))=3))
And If you want to avoid more than one space between the number( Example: 044 123 45678)
Paste this:
IS_NOT_NULL(Phone Number) AND LEFT(Phone Number,1)<=1 AND IF(LEFT(Phone Number,1)=1,ABS(Phone Number)=Phone Number) AND (IF(LEFT(Phone Number,1)=0,LEN(ABS(Phone Number))=2 OR IF(LEFT(Phone Number,1)=0,LEN(ABS(Phone Number))=3)) AND IF(LEFT(Phone Number,1)=0,ABS(RIGHT(Phone Number,LEN(Phone Number)-LEN(ABS(Phone Number))-2)) = RIGHT(Phone Number,LEN(Phone Number)-LEN(ABS(Phone Number))-2)))
